Description

Field of the Invention

The present invention relates to the field of vehicle interior parts, and in particular to a vehicle pillar interior trim panel and a vehicle.

Background of the Invention

A vehicle pillar is an important supporting component on a vehicle body. Customarily, pillars on one side of a vehicle from the headstock to the tailstock are called an A-pillar, a B-pillar, a C-pillar, and so on. A vehicle pillar interior trim panel is an interior trim part covering the interior of a vehicle pillar, and a safety belt webbing is generally arranged to pass through the pillar interior trim panel. Furthermore, on the pillar interior trim panels of some vehicle models, for example, a safety belt sliding plate structure (also called a safety belt height adjustment baffle) is also arranged on an upper interior trim panel of the B pillar to adjust the height of the safety belt.
The existing vehicle pillar interior trim panel has the following shortcomings:
Firstly, in order to reduce the gap between a B-pillar trim panel and a door trim panel, the upper interior trim panel of the B pillar of the existing vehicle is often made into an inverted draft structure. However, for the upper interior trim panel of the B pillar with a safety belt sliding plate, the pillar interior trim panel of the inverted draft structure is easily extruded by a sealing strip to deform, thereby leading to unsmooth movement of the safety belt sliding plate. One improvement method is to weld a rectangular frame with high strength on the inner side of the pillar interior trim panel to support the two sides of the pillar interior trim panel to prevent the deformation thereof, but this will greatly increase the manufacturing cost of the pillar interior trim panel and the material cost.
Secondly, on the vehicle model with side air curtains, in order to conveniently detach the pillar interior trim panel, the pillar interior trim panel is often fixed to the vehicle body by screws. In this manner, a detachable bulkhead cover needs to be arranged to detach the pillar interior trim panel, such that the appearance is unattractive.
In addition, when the pillar interior trim panel with the safety belt sliding plate is installed, when a bolt connection hole of the safety belt sliding plate is aligned with a safety belt bolt, the safety belt sliding plate is prone to move, resulting in inconvenient installation and increasing the difficulty of installation.
EP 0736422A2 discloses a trim component for mounting to a structural member of an automotive vehicle including a body fixedly mounted to a structural member, the body including a plurality of energy absorbing ribs spaced relative to one another along the body and disposed adjacent to the structural member when the trim component is mounted thereto. The energy absorbing ribs include a series of fingers extending from the body and spaced relative to one another. The fingers deflect upon contact with the structural member in response to a force acting on the body to absorb and dissipate the energy generated by the force.
CN 104442685A discloses a safety belt motion mechanism of a B column interior trimming panel assembly. The safety belt motion mechanism comprises a B column interior trimming panel body, a safety belt slide plate and a height adjustment button, wherein the B column interior trimming panel body is provided with a safety belt slide plate mounting hole, a plurality of safety belt slide plate clamping pins and safety belt slide plate slide way slide channels; a height adjustment button mounting hole, a safety belt outlet, height adjustment button slide channels and safety belt slide plate slide rails are arranged on the safety belt slide plate; the height adjustment button is provided with a pressed protrusion part and height adjustment button slide grooves, and slidably mounted on the back surface of the safety belt slide plate; the safety belt slide plate is slidably mounted on the back surface of the B column interior trimming panel body; a spring for resetting the height adjustment button is arranged between the safety belt slide plate and the height adjustment button.
